Add handleAlive in logs for child layers for layer leaks.

It is useful to judge whether the SurfaceControl of this child layer
is released when the layer leak issue happened because child layer
won't be added to mOffScreenLayers when its LayerHandle is destroyed,
so we can not get its handleAlive in dumps or logs of offscreenlayer.

Test: logcat
